Hyundai
Veloster

While driving at approximately 70MPH on the highway, my 2014 Hyundai Tucson Limited suddenly locked up with no warning lights, no noise and no prior symptoms. The engine completely seized, causing immediate loss of power. I was barely able to coast off the highway exit to a final stop on the feeder shoulder, in a desolate area. The vehicle has always been properly maintained and is in excellent condition. Upon research, I learned that Hyundai has known of internal engine defects caused by metallic debris left from manufacturing since 2010, which can cause bearing failure and engine seizure. My Tucson's failure matches the same pattern described in Hyundai's Theta II engine recall and warranty extension campaigns. This sudden failure created an extremely dangerous situation at highway speed and possibility of injury while being stranded on an open road. Many owners, myself included, were never properly notified of the risks. I am filing this report because this incident represents a serious safety defect and potential recurrence among similar vehicles that may not yet be covered by recall. I respectfully request that the National Highway Traffic Safety Administration investigate this issue and ensure Hyundai expands its recall and warranty coverage to include affected 2014 Hyundai Tucson Limited vehicles exhibiting this defect that was well-known to the Hyundai Corporation. Date of Incident: October 23,2025 in Houston Texas. Vehicle towed to Hyundai dealer which diagnosed Engine Seized and currently awaiting Warranty Extension Approval (TXXC/TXXI)

The car lost power gradually ;when I was driving ; We were on the freeway and I couldn’t continue driving 60 miles per hour , therefore I turned on the turn signals cause I just could drive at 35 miles per hour and the car just start shaking ; I just look for the next exit by the time We were on risk on the emergency lane for along time cause the next exit was to far from there .and the car was too slow ,when we finally got exit I call and I stop my car and call the mechanic to ask for help and he help me plug in the scanner machine to my car and there was a problem with some cylinders and one valve and I decided to called to the dealer to get an appointment:. My Vehicule already was checking for Hyundai but they just text me a message ; they said my car needs to replace a motor ,turbo ; some broken valves causing zero pounds of compression on cylinder 4-long block repair-new intake and exhaust manifolds (including turbo)required due to broken valve sending metal through the entire system -quote long block/intake and exhaust manifolds /turbo /all necessary gaskets and fluids for repair : I just was noted my car was consuming too much oil, cause the car board showed me 3 weeks ago and I need to add oil ,and the mechanic plugged in the scanner; but it doesn’t showed something else ;therefore 3 weeks ago I added 1/4 or more ; then was 2 week ago; I added 1/4 of oil again and then just last week I added 1/4 or more oil again ;I just was checking the oil constantly.; and it should be noted that the car was not leaking oil but I didn’t understand why it was running out so quickly .
